Question

4. A 15 ohm and a 60 ohm
resistances are connected in
parallel to each other and this
combination is connected in series
with a 40 ohm resistance. If the
PD is 10 V calculate the current
and the effective resistance​

Answer 1

Answer:

current is 5/26 ampere. effective resistance is 52 ohm

Explanation:

(1/15+1/60)=1/Rp

4+1/60=1/Rp

12=Rp----[1]

12+40 = Rs

52=Rs=Reff

I=V/R

I=10/52

I=5/26
